Description

2. Pattern device according to claim 1, characterized in that the leading edge (37) of the Locking lever (20) is rounded.

The invention relates to a pattern device for circular knitting machines with stacked one above the other arranged and manually in the horizontal direction between an advanced effective Position and a withdrawn ineffective position displaceable pattern slider, whose side edge has at least one recess which cooperates with a locking part.

From DT-PS 6 23 775 a sample device of this type is already known in which each Sample slide is assigned its own non-positive positive locking position. Thereby the sample slide held by means of tension springs with their recess on the rugeorderen locking part in contact. As a result, many items are required and the assembly and adjustment of the pattern device is difficult and time consuming. The function of this position security is also relatively uncertain, because the adjustment of the sample slide takes place under the force of the partially relaxed springs.

In the documents of the DT-Gbm 19 55 041 a sample device is described in which every Sample slide is assigned its own position security. This position security has compression springs that They are more disadvantageous than tension springs because they tend to buckle to the side.

The invention is based on the object of the fiattungsgemäße sample device with regard to To simplify the position of the sample slide structurally and to make it more reliable.

According to the invention, this object is achieved in that in the side edge of each pattern slide crs two recesses are provided, the effective and ineffective position of the MusRrrschiebcrs correspond to the fact that the locking part is a pivotable locking lever. its horizontal Pivot axis at a distance above the topmost sample slide of the stack and in relation to the sample slide Is arranged eccentrically, and JaIi the locking lever can be locked in the Sperrstellimg.

The essential Arbe.tselemente a Rundstnckmaschine are needles 1. Musterscnwingen t liiiü leaf-shaped pattern shifter 3 for controlling the first-mentioned parts. Springs 23 and 24 are used to hold the sample rockers 2.

A needle pusher 6 is assigned to each of the needles 1 provided with a hook 4 and a foot 5

a lock channel 7 of a lock part 8 engages, aut which the foot 5 of the needle 1 rests. The pattern swings 2 have a rear approach 9, aul the de, Needle pusher 6 rests, and a front stop 10, who works with the sample slide 3

The stacked one on top of the other Sample slide 3 are in a fixed I rager 11 horizontally displaceable. The carrier 11 is secured to an angle iron 12 by means of screws 14 connected, which in turn is attached to the frame ring 13 of the circular knitting machine by means of screws 28. At the frame ring 13 is a rear cover 25

Furthermore, a locking lever 20 is provided which is around a

Flat spacers 32 can be between the

Pattern slide 3 are used to determine the exact distance between them so that they are with the Attacks 10 of the sample swing arms 2 exactly match

If the pattern slide 3 for a certain!

If patterns are selected, one begins first with the top sample slide of the unit. Is

the locking lever 20 is raised so as not to hinder this operation. The first sample slide 3, like all the other sample slide, has two recesses V

And 35 on which of the effective and the ineffective Corresponding position, and it is arranged so that one of these recesses is opposite the locking lever 20, whereupon the locking lever under the influence of gravity into the relevant recess falls into it. This keeps the sample slide and the locking lever in the correct working position JO lies against an area between the recesses 34 and 35 of the next lower pattern slide.

In the case of the second sample slide, the setting process takes place in a similar manner, in that the locking lever 20, the one of the recesses 34 or 35 opposite, lintet its own weight a little further into the relevant recess falls into it and thus holds the second sample slide in place. The other sample sliders 3 are sequentially positioned and held in a similar manner until the bottom Pattern slide is reached, whereupon the locking lever 20 reaches its locking position in which it is with the Screw 22 is locked, so that in this way the pattern swing against horizontal displacement are secured.

A more regular and constant adjustment of the locking lever 20 to the! viusterschieber 3 during the To achieve the election process explained above, its front edge 37 can be rounded.

To work together in the above Way to ensure that the screw 21, around which the locking lever 20 rotates, in is arranged eccentrically with respect to the pattern slide 3.

The screw 22 holds the locking lever 20 by engages in a recess 38 of the lever.

There is also a numbered scale Ϊ9 provided, through which each individual sample slide i is localizable.
